This page simulates a blogger mentioning that they have an item for sale, and recommending two books. The blogger need only add a small amount of RDFa, and the Ubiquity library does the rest:

Note that there is a bug in YUI which will cause the eBay tooltip to be nothing but a flashing white box if the browser window is too small.

My Blog

I would really recommend Canteen Cuisine and Conversations with Glenn Gould ...they're both great books.

Also, I saw this bike for sale and it might suit someone who hasn't already got a bike exactly like it.
